I suggest eliminating the dependency on the working directory completely.
For example, you can pass the location of necessary data files to the
test programs via environment variable(s) or command-line arguments. If
all your data files are in one place this might be something simple like:
UNBOUND_TEST_DATA=${srcdir}/testdata ./the_test_program
and the test program can construct filenames based on that environment
variable.
Environment variables are convenient. Command line arguments to the
test program are also convenient. If the test program is also the
installed program, take care that security or reliability issues are
not introduced due to responding to environment variables.
Microsoft Windows has very limited command line plus environment space
(come out of same allocation) so take care not to use so much
resources that it is not possible to run the tests under Windows (if
Windows is supported).
